Abstract

A method of separating and feeding sheets from a stack comprises the steps of bringing a pick-up head into engagement with an intermediate portion of the top sheet of the stack while leaving the opposite ends of the sheet free, applying an air stream from each of the opposite sides of the stack and directed inwardly to impinge against the stack and to cause the free ends of the top sheets of the stack to separate from the underlying sheets, and moving the pick-up head with the picked-up top sheet away from the stack.
